Choose the Right Data Storage Option .NET MAUI

In today’s digital age, mobile apps have become an integral part of our lives. Whether it’s for productivity, entertainment, or socializing, we rely on apps for various tasks. .NET MAUI (Multi-platform App UI) is a powerful framework for building cross-platform apps, allowing developers to create apps that run seamlessly on Android, iOS, and other platforms. When developing .NET MAUI apps, effective data handling and storage are crucial for a smooth user experience. In this article, we’ll explore best practices for data handling and storage in .NET MAUI apps, ensuring that your app performs efficiently and securely.

Choose the Right Data Storage Option

.NET MAUI apps often need to store and manage data, ranging from user preferences to application-specific content. Choosing the appropriate data storage option is the first step in ensuring efficient data handling. Here are some common options:

UserDefaults (iOS) and SharedPreferences (Android): Suitable for storing small amounts of data like user settings and preferences.

SQLite: Ideal for structured data and complex querying.

Xamarin.Essentials Preferences: Cross-platform key-value pairs storage.

Cloud-Based Storage: For remote data storage and synchronization.

The choice of storage depends on your app’s requirements. For complex data structures and queries, SQLite is often the best choice, while UserDefaults and SharedPreferences are suitable for lightweight storage.

Implement Data Access Layer (DAL)

To maintain a clean and organized codebase, it’s essential to implement a Data Access Layer (DAL). The DAL abstracts the underlying data storage, making it easier to switch between different storage options without affecting the rest of the application. It also promotes code reusability.

Asynchronous Data Operations

In .NET MAUI apps, data operations should be performed asynchronously to prevent blocking the UI thread. This ensures a responsive user interface, even when dealing with large datasets or slow network requests. Utilize async and await keywords when working with data operations.

Secure Data Storage

Security is a top priority when handling user data. When dealing with sensitive information, such as user credentials or personal data, follow these best practices:

Encryption: Encrypt sensitive data before storing it.

Secure Communication: Ensure data transmission is done securely using HTTPS.

Authentication and Authorization: Implement proper mechanisms to restrict access to sensitive data.

Data Caching and Offline Support

Implement data caching strategies to store previously fetched data locally, allowing the app to provide a seamless user experience even without a network connection. Consider using libraries like Akavache or MonkeyCache to simplify data caching in your app.

Data Synchronization

Implement synchronization mechanisms to keep local and remote data in sync, handling conflicts and managing data updates intelligently.

Proper Error Handling

Ensure your app gracefully handles errors, providing clear and user-friendly error messages. Log errors for debugging purposes but avoid exposing sensitive information to end-users.

Testing and Optimization

Thoroughly test your data handling and storage components and profile your app to identify performance bottlenecks. Optimize data access for improved responsiveness.

User Data Privacy

Respect user data privacy by adhering to data protection regulations and clearly communicating your app’s data collection and usage policies to users.

Regular Updates and Maintenance

Regularly update and maintain your data management strategies to accommodate new features and changing requirements, ensuring your app remains secure and efficient.

In conclusion, data handling and storage are fundamental aspects of building .NET MAUI apps. By following these best practices, you can create reliable and user-friendly apps that users can trust and enjoy.

UserDefaults iOS Tutorial

With the UserDefaults class, you can save settings and properties related to application or user data. Any data saved to the defaults system will persist through application restarts. In this tutorial we will save the state of a switch, so this state is saved when the app restarts. This tutorial is made with Xcode 10 and built for iOS 12.

Open Xcode and create a new Single View App.

For product name, use iOSUserDefaultsTutorial and then fill out the Organization Name and Organization Identifier with your customary values. Enter Swift as Language and choose Next.

Go to the Storyboard and drag a Label to the left side of the view. Select the Label and give it a title of "Bluetooth". Next, drag a Switch Next to the Label. The Storyboard will look like this

Build and Run, and change the switch to Off. Exit the application and start it again. As you can see the previously selected state isn't persistent through application restarts.

�� Select the Assistant Editor and make sure the ViewController.swift is visible. Ctrl and drag from the Switch to the ViewController class  and create the following Outlet.

Ctrl and drag from the Switch to the ViewController class  and create the following Action.

Go to the ViewController.swift file and implement the saveSwitchState method

@IBAction func saveSwitchState(_ sender: Any) { let defaults = UserDefaults.standard if bluetoothSwitch.isOn { defaults.set(true, forKey: "SwitchState") } else { defaults.set(false, forKey: "SwitchState") } }

We create a UserDefaults object, where we can save the user settings. Next, we save the current switch state as a Boolean value in the Switchstate key. Next, change the viewDidLoad method

override func viewDidLoad() { super.viewDidLoad() let defaults = UserDefaults.standard if (defaults.object(forKey: "SwitchState") != nil) { bluetoothSwitch.isOn = defaults.bool(forKey: "SwitchState") } }

We check if there is a previously created SwitchState key, and if so we load the state and change the switch. Build and Run, change the switch state to Off. Restart the application and you will see the switch still is in the off state.

You can download the source code of the IOSUserDefaultsTutorial at the ioscreator repository on Github.

Swift Keyboard Control for TextFields and TextViews

Keyboard Control as User Navigates TextFields and TextViews on Table View Form

Scenario

Our app will allow users to tap between TextFields and TextViews and control the keyboard display (hide or show) as required. The code will ensure that the keyboard does not override (hide) the TextField or TextView the user has in focus.

Technique

We shall utilise the Delegate feature so the view, as the delegate to the TextFields and TextViews, can control the keyboard display. Then we shall use GestureRecognizer to detect user gestures and check the TextField or TextView BeginEditing and EndEditing conditions and animate the fields or views to move them up or down, depending on the keyboard display status.

Audience

The article is for Swift developers who seek complete, integrated, proven, code-centric solutions to speed up their development projects.

App Model

We based the article on the AppsGym Books model app, published on Apple’s App Store (as 8Books), and you can download the complete Xcode project on AppsGym.com, for free.

User Interfaces

NewBookTableViewController.swift and EditBookTableViewController.swift control the layout, order, and navigation of the corresponding UITableViewControllers.

Logic

NewBookTableViewController.swift contains keyboard control logic, which monitors and detects user taps on the form fields and reacts accordingly.

There are 7 TextFields on the New Book view: Title, Author, Series, No in Series, Category (Genre), Source, and Format. Each field has a Tag on the Storyboard (e.g., titleTextField.tag = 1) and each behaviour is governed by 3 textField functions, which we shall utilise to control the textField attributes and movement by controlling the becomeFirstResponder() function.

textFieldShouldReturn(..), textFieldDidBeginEditing(..), and textFieldDidEndEditing(..)

There are 2 TextViews on the New Book view: Synopsis and Notes. We shall use 2 textView functions to control their behaviour: textViewDidBeginEditing (..) and textViewDidEndEditing(..).

Code

We shall separate the code of TextFields and TextView to make it easier to focus on each group keyboard control.

TextFields

NewBookTableViewController.swift Initialise Variables

// Tags are used to Auto Jump to next TextField; see func textFieldShouldReturn    @IBOutlet weak var titleTextField: UITextField!        { didSet {            titleTextField.tag = 1            titleTextField.delegate = self    }  }    @IBOutlet weak var authorTextField: UITextField!        { didSet {            authorTextField.tag = 2            authorTextField.delegate = self    }  } ...    @IBOutlet weak var formatTextField: UITextField!        { didSet {            formatTextField.tag = 7            formatTextField.delegate = self    }  } ....

NewBookTableViewController.swift viewDidLoad()

...       let tapGestureReconizer = UITapGestureRecognizer(target: self, action: #selector(NewBookTableViewController.tap(_:)))        view.addGestureRecognizer(tapGestureReconizer) ...       }

NewBookTableViewController.swift Keyboard Control

   func textFieldDidBeginEditing(_ textField: UITextField) {        textField.layer.borderWidth = 2        textField.layer.borderColor = UIColor.orange.cgColor    }         func textFieldDidEndEditing(_ textField: UITextField) {        textField.layer.borderWidth = 0        textField.layer.borderColor = UIColor.clear.cgColor    }

   @objc func tap(_ sender: UITapGestureRecognizer) {        view.endEditing(true)    } view raw

TextViews

NewBookTableViewController.swift Initialise Variables

class NewBookTableViewController: UITableViewController, UITextViewDelegate { ...    @IBOutlet weak var synopsisTextView: UITextView!    @IBOutlet weak var notesTextView: UITextView!  ...  

ewBookTableViewController.swift viewDidLoad()

override func viewDidLoad() {        super.viewDidLoad() ...        self.synopsisTextView.delegate = self    // keyboard control        self.notesTextView.delegate = self    // keyboard control        synopsisTextView.text = ""        notesTextView.text = "" // stringCurrentDate() + "nn" ...        let tapGestureReconizer = UITapGestureRecognizer(target: self, action: #selector(NewBookTableViewController.tap(_:)))        view.addGestureRecognizer(tapGestureReconizer) ... } // end viewDidLoad()

NewBookTableViewController.swift** Keyboard Control**

/ 4 funcs To dimiss keyboard and move the textView UP/Down when the keyboard shows    @objc func tap(_ sender: UITapGestureRecognizer) {        view.endEditing(true)    }        func textViewDidBeginEditing(_ textView: UITextView) {        textView.layer.borderWidth = 2        textView.layer.borderColor = UIColor.orange.cgColor        animateViewMoving(true, moveValue: 100)    }        func textViewDidEndEditing(_ textView: UITextView) {        textView.layer.borderWidth = 0        textView.layer.borderColor = UIColor.clear.cgColor        animateViewMoving(false, moveValue: 100)    }        func animateViewMoving (_ up:Bool, moveValue :CGFloat){        let movementDuration:TimeInterval = 0.3        let movement:CGFloat = ( up ? -moveValue : moveValue)        UIView.beginAnimations( "animateView", context: nil)        UIView.setAnimationBeginsFromCurrentState(true)        UIView.setAnimationDuration(movementDuration )        self.view.frame = self.view.frame.offsetBy(dx: 0,  dy: movement)        UIView.commitAnimations()    }

**

**

Keyboard Height

The code snippets above used a simple moveValue of 100, which would suffice for most scenarios. However, a more accurate measure would be the actual keyboard height on the device.

The code snippet below shows how to obtain the Keyboard Height. If you want to use this method, substitute the keyboardHeight for the ‘100’ in the moveValue argument for TextView. You can optionally use keyboardHeight in the TextField functions for more precise controls.

       if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {          keyboardHeight = keyboardSize.height          print(#function, keyboardHeight)

           // The 1st keyboardWillShow gets the keyboard size height then observer removed as no need to get keyboard height every time it shows or hides

           NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillShowNotification, object: nil)                        // Store KeyboardHeight in UserDefaults to use when in Edit Mode

           UserDefaults.standard.set(keyboardHeight, forKey: "KeyboardHeight")            UserDefaults.standard.synchronize()        }    } // end func keyboardWillShow

The article covered the complete logic and code to control the behaviour of TextFields and TextViews, so the keyboard does not obscure the relevant fields or views behind it. Hope you find it useful in your app. Thanks for reading!

Apptober: Day 6

Woot, Siri now understands, in a suuuuper basic and templatey way, how to set the Right Meow status!

Since it's easier to test with the iPhone simulator than the watch simulator, I decided to start implementing the Siri extension on the iPhone-half of the app first. This revealed two main problems:

Siri's ability to grasp the pronunciation of "Right Meow" is sadly limited out of the box (an expected outcome, really).

Syncing data across all of an app's extensions is a process filled with more goat-stealing trolls than a fairytale bridge (sad, but also expected.)

1. I Thought I Heard You Say “Right... Meow”?

I can't get mad at Siri for having trouble with this one. Siri understands the pronunciation of "Right Meow" in the context of "Launch the app Right Meow!". However, in the context of “create a reminder RightMeow” she autocorrects to "Right Now", because that's probably what most people want (I mean, duh).

Apple helpfully provides an API for supplying Siri with extra vocabulary that's specific to your app, so tomorrow I'll look into expanding Siri's vocabulary with some extra Intent Phrases and Parameter Vocabularies that will make her a RightMeow champion.

For now I’ve just been testing my Intents implementation with an Xcode run scheme that provides a written Intent Query Siri can for sure understand:

2. I Sync, Therefore I am 

The thing about extensions (which Siri and watch face complications are), is that they’re run in environments outside your main app. This means you need a way to sync data between your apps and these extensions. Enter App Groups! 

Using app groups was tantalizing because I barely had to change my implementation for storing data (I’m just using UserDefaults). All I had to do was change a few project settings and BAM - theoretically all my extensions would be reading from the same place!

This worked great for exchanging data between the Siri extension and my main app because they both run on the some device. Unfortunately this failed spectacularly when it came to syncing data across the watch app, the watch extension, and the main app. 

At one point all three of my main apps/extensions were sporting data with different levels of freshness, as I’ve illustrated with incredible artistic precision:

Either I’ve made an interesting configuration error or this is just UserDefaults making excellent and depressing use of caching. I’m probably gonna have to come up with a better way to store data if I want to sync it reliably between watch, phone, and extensions.

Tomorrow:

Tomorrow’s tasks are legion: update Siri’s vocabulary, give her a better response template, and maybe even find a good way to keep data synced across our devices. If I’m feeling super ambitious I might even look into iCloud for syncing.

We'll make use of a UITableViewController to display our tasks and apply MVC and Dependency Injection to ensure separation of concerns. What's a to-do list without a way to save it? Storing the tasks will be possible because of UserDefaults and archiving. Taskly will be built from the ground up and even intermediate programmers will be able to pick up useful concepts and information from this course. There's a lot of questions that will be addressed, such as, what design patterns should we use? Once we're satisfied with how the app looks, we'll get to compare it with the original design mocks to see if our work meets expectations.  All in all, Taskly will quickly fill any gaps in knowledge you have about building an iOS application and set a foundation up for you to build your own apps. What are the requirements? Xcode 9.2 or greater Have a basic understanding of how to program in Swift What are you going to accomplish in this course? Building an entire application from the ground up that you can use immediately The idea of thinking more from a design perspective to ensure that we're writing good code Who this course is for: Anyone who wants to apply their knowledge of Swift into developing a useful iOS application This course was designed for the beginner to intermediate Swift programmer Created by Justin Rose Last updated 1/2019  English  English Google Drive https://www.udemy.com/ios-swift-build-a-to-do-list-app/?utm_source=careers24&utm_medium=web&utm_campaign=careers24octlaunch&pmtag=CAREERS24LEARN15&aff_code=Ewh3Y1xWRnkGRR5zMkBPbG1RGXFfVFh8CF4ac05QRHYBShFxWT5XMRM= Read the full article

Course description:

This course will show you that building iOS apps with Swift 3 is fun and easy. Learn how to create 17 apps using Apple’s  new programming language Swift 3. Each project will build on the previous one, reinforcing what you have just learned, step by step, so theres no guesswork as to the process and what the code is doing. We go over each line and see what it’s doing, this is a great way to learn about the Cocoa touch classes, frameworks, methods, and everything iOS. The course makes use of callout graphics, diagrams, highlighting, and deep explanations to help guide you along the path of the code, so its easy to follow. When you understand how to put together one project, you can proceed to the next one with confidence, and implement your new skills as you go along. The author of these carefully crafted projects is the award winning Swift programmer, “Paul Hudson”. You can check out all of his work at hackingWithSwift,com. Paul and i teamed up to take many of his written tutorials and convert them into lecture format courses. He is among the top Swift programmers, and has received high praise from the creator of the Swift language, Chris Lattner, for his outstanding tutorials and method of teaching iOS, so you know your getting the best of the best here. This course also makes the perfect reference tool kit, to be used in conjunction with the Apple docs, so that you can go back and scrub through any of the lectures very quickly to pull out relevant code or instruction that you need, as there’s no wasted chatter here, it’s strictly on point with iOS.

Some of what you will be leaning:

Featuring apps built by the award winning Swift programmer – Paul Hudson – hackingwithswift,com We use Xcode 8.2.1 – The latest version The Swift 3 language – we go from variables to creating our own functions and more Learn Swift by use of diagrams / highlighting / graphics  Learning the ins and outs of Xcode 8  Working in storyboards and all it nuances  How to use with controls / Outlets and Actions  How to use logic for smooth control flow Using segues and passing data, in storyboards, and programmatically Master table and collection view controller Using delegates and protocols Work with the social framework – FB – Twitter etc. Learn how to refactor code The ins and outs of GCD SpriteKit and Games The new UserDefaults to persist data Adding audio / Animations Master strings in Swift 3 Using stackView The safari view controller class Using core image Learn the best debugging techniques Create an extension for your app

Reviews:

“I’ve taken all of Stephen Destefano’s courses at Udemy. What I love about him is his clear voice and explanation of each topic, from beginner to advance. He answers all his students questions with respect and clear responses knowing that we are beginners to his class. Highly, highly, highly recommend ALL his courses.” (Annabelle Ramos)

“This is a very informal course. He explains everything thoroughly and breaks it down. I’m coming from zero background in code so my learning is just like explaining 2+1 to a 4yr old. It takes time and effort. However Stephen has taken the time to reach back out every time I’ve had a question and will precisely break things down to a minute level. I’m learning a ton and finally understanding what I’m writing instead of just blindly typing.” (David Groomes)

“I almost took.5 off because I am not sure that this is for an abject beginning programmer to be. There are concepts being introduced that I am not sure a non-programmer would grasp so early, at least would have been for me. I am using this to fill in holes in my understanding of swift. I understand so much more now. This is an excellent course and I am happy that I am taking it. Peace, Myst.” (Donald Bradbury)
